16 2.6 TURNING THE UNIT ON AND OFF Turning the unit ON The unit is turned on by actuating on the power switch of the rear panel The DRO runs a self-test and shows on thelcd display the text: Fagor NVPxxx M, Press C (where xxx indicates the model) and the X and Y displays show "Fagor dro" if everything is OK and the error number if otherwise. See the appendix at the end of this manual. Turning the unit OFF If you press the DRO turns off the displays while maintaining the power supply to the feedback systems and goes on reading the position of the axes at all times. This is not the case when the equipment is switched off by means of the switch on its rear panel. To reset the displays, just press this key again, on condition that the DRO is getting voltage (plugged in and with the switch on the rear panel on). Notes: - Before powering the DRO down with the switch on the rear panel or disconnecting it from mains, it is a good idea to press the key in order to store the current position of the axes permanently. - If the unit is powered down with its rear panel switch or there is a power outage without previously having pressed, the DRO will keep the last position of the axes for at least 30 minutes. - The unit will display ERROR 2 when powered back up if the position reading was lost when turned off while the axes were moving or after the accidental backup period has expired without having saved the current position by previously pressing.

17 3. INSTALLATION PARAMETERS These DROs have a number of installation parameters to configure it for a particular application. These parameters may be saved into a peripheral or uploaded from it through the RS-232-C serial communications line. The format for these parameters depends on whether they are general or particular for each axis.. If it affects the axes, press the corresponding axis key to modify it.. If it is a general parameter, the X display will show its current value.. The LCD display will show the description of the parameter and its number. There are several kinds of parameters depending on how to set them: With binary values. The value of each digit toggles between "0" and "1" when pressing its corresponding key from to where corresponds to the rightmost digit and to the leftmost one. Numeric values, usually with the corresponding axis resolution, they are entered as regular preset. Options, the value is changed by pressing + - options appear in a cyclic way. which will make the various Note: On "NVP400M" and "NVP401M" models, parameters 00, 01, 02, 03, 04 and 14 of the 4th axis may be edited by pressing F while editing the corresponding PAR??. Its value will appear at the X axis display. These values are ignored if the axis is coupled with another one since those of the main axis will be taken.

18 3.1 PARAMETER SETTING The DRO display must be on and in counting mode in order to be able to edit the parameters.. Press F. The LCD display will show the menu: SPECIAL UTILIT. / PARAM / COMM. Select "PARAM" using the keys.. When the word "PARAM" appears between < >, press ENTER. The LCD display requests the password ( ). If it is not entered, it is still possible to edit those general parameters not affecting the axes. The LCD display will show the parameter number and a brief description.. If it is a general parameter (not affecting the axis reading), the display will show its current value.. If it is an axis parameter, each axis display will show its current value. In this case, press the axis key (X, Y or Z) and key in its new value. - To go from one parameter to another and save the changes: Press ENTER or to go to the next one. To go to the previous one, press 1 2 or - Pressing another axis key, (X, Y or Z), the DRO saves the value of the previous axis and shows the new axis to be edited. - To quit the parameter editing mode, press C and the DRO will recover the previous values ignoring the changes just made. From the count modes, it is also possible to access all the parameters not affecting the count (user), such as: parameter PAR50 (language) with the keystroke sequence: C and PAR05 (scaling factor) with the keystroke sequence: C. This way, it is possible to change operating modes without having to go through all the parameters preceding the ones we would like to edit. This is also possible for parameters PAR40 through PAR45 (I/O), PAR51(memory lock), PAR90 through PAR93 (RS-232-C serial line). Page: Installation Manual NVP-300M/301M Man: 9910 Soft: 2.xx

Factory setting: "1" one must press the axis PAR12 To set the negative axis travel limit. Possible values: between and 0. Page: Installation Manual NVP-300M/301M Man: 9910 Soft: 2.xx

23 This value will be in mm or inches depending on whether the INCH LED is off or on. If PAR08=1(alarms ON), when the axis exceeds this distance, the corresponding axis display starts blinking until it is moved back into the work zone. Note: When a rotary axis, the setting of this parameter will be ignored. PAR13 To set the positive axis travel limit. Possible values: between 0 and This value will be in mm or inches depending on whether the INCH LED is off or on. If PAR08=1(alarms ON), when the axis exceeds this distance, the corresponding axis display starts blinking until it is moved back into the work zone. Note: When a rotary axis, the setting of this parameter will be ignored. PAR 14 To carry out the home search when the feedback device does NOT have reference marks "Io" (for example, FAGOR MKT scales), this parameter must be set to "1". Factory setting = "0". PAR 15 Contains the leadscrew error compensation. Enter the number of points to be compensated (up to 40). "0" means that no compensation is to be applied. - When pressing, the X axis display shows the position value ENTER and the Y axis display shows the error to be compensated. Use the ENTER and 1 2 to move from point to point. - Use the axes keys to edit the position or the error with the resolution and units of the axis (PAR00 and PAR01). - When pressing, the X axis, shows the home coordinate of the selected axis. When pressing or the dro assumes the displayed ENTER coordinate as the error position and it then requests the amount of error to be compensated. This error amount is the "Actual position - Displayed position". The Home point (Io) must be assigned an error of "0" - The preset is canceled by pressing before pressing ENTER. - To exit, press when none of the axes is blinking.

24 3.3 INPUT/OUTPUT RELATED PARAMETERS PAR21 Indicates the active level for the inputs. Only the first four digits are used where the first one corresponds to "E1" and the last one to "E4". A "0" indicates that the input is active low (0V). E1, E2 and E3 are used to zero the reading of the X, Y and Z axes respectively and E4 as Emergency signal. PAR23 Indicates the active level for the outputs. Only the first six digits are used where the first one corresponds to output "S1" and the last one to "S6". A "1" indicates that the output is active high (5V or 24V). It must be borne in mind that the outputs are activated when the axis position is equal to or more negative than the preset value and they go high "1" or low "0" depending on the setting of machine parameter PAR23. PAR30 These parameters set the axis number controlling its corresponding to signal. PAR30 corresponds to S1... PAR35 to S6. PAR35 It admits values from "0" to "3" where "0" means that the signal is not being used, 1 = X, 2 = Y, 3 = Z. PAR40 to PAR45 They set the signal activating positions (levels) of the axes indicated by PAR30 through PAR35. The PAR40 coordinate is used to activate signal "S1",... and the PAR45 coordinate to activate "S6". This value will be in mm or inches depending on whether the "INCH" LED is off or on.

After pressing C to access the counting mode, check the parameters. If any of the errors shown as (Service Department) are often repeated, ask Fagor Automation s Customer Services Department about this. If the display of some axis shows all its decimal points; for example: this means that the axis has moved at a greater speed than what is required for its reading (>200 KHz or 60 m/min. with 1µm resolution). This error is displayed if the alarm activation parameter for the axis PAR08 = 1. To clear the display, press C. If the axis value is flashing, this means that one of the travel limits established by machine parameter has been exceeded. This error will be displayed if the alarm activation parameter for the axis PAR08 = 1 If the DRO does not come on or goes out while running, check that the voltage and ground outlets are as they should be. If no anomalies are found in them, disconnect the feedback connectors one by one. If the DRO comes on this indicates a fault in the feedback device. If the fault persists get in touch with Fagor Automation s Customer Services Department about this. NVP-300M/301M Man: 9910 Soft: 1.xx Manual de Instalación - Página: ap.1

30 MAINTENANCE Cleaning: An accumulation of dirt in the equipment can act as a screen preventing proper dissipation of the heat generated by the internal electronic circuits with the consequent danger of overheating and DRO fault. Accumulated dirt can also, in some cases, provide a conductive path for electricity which could give rise to faults in the internal circuits of the equipment, especially in high humidity conditions. To clean the equipment nonabrasive dish-washing detergents are recommended (in liquid, never powder form) or 75% isotropic alcohol with a clean cloth. DO NOT USE aggressive solvents, (benzol, acetones, etc.) which could damage the materials the equipment is made with. Do not use high pressure compressed air to clean the item as this could give rise to an accumulation of charges which in turn lead to electrostatic discharges. The plastics used in the front panel of the DRO stand up to: 1. Grease and mineral oils. 2. Alkalis and bleaches. 3. Dissolved Detergents. 4. Alcohol Avoid the effect of solvents such as Chlorohydrocarbons, Benzol, Esters and Ethers because these could damage the plastics with which the front of the equipment is made. Preventive Inspection If the DRO does not come on press the rear switch for starting, make sure it is properly connected and being supplied with the proper mains voltage.

33 INTRODUCTION Throughout this manual, certain installation parameters are referred to which affect the description of certain DRO functions. These parameters have been set by the installer and may be modified by the operator. These parameters are described in the installation manual supplied with this unit. 1. UNIT DESCRIPTION This DRO is designed for industrial environments, especially for machine tools. It can display the position of two, three or four axes of the machine and run repetitive parts. 1.1 FRONT PANEL LCD display The LCD display offers assistance for the various operations possible with this unit. - NVP-M - Operation Manual - Page: 1.1 -

34 Each axis display has eight 14.1mm high LEDs and another one for the minus sign (-). ABS-This lamp stays on when operating in absolute mode and off when in incremental mode. To access or quit this mode, use the key. φ - This lamp stays on when operating in diameter mode. In this mode, the DRO displays twice the actual axis movement. To access it or quit it, use the key (if allowed by PAR04) HOLD- INCH- This lamp comes on when "freezing" the axis position by pressing and the axis key. This lamp stays on when working in inches and off when doing it in millimeters. To access it or quit it, press This lamp stays on during machine reference search. See the section on references. TOOL- This lamp stays on when working with tool compensation. "PROBE" This lamp goes on when selecting the "probe" mode. Keys to select the first the second and third axis respectively. Is used for changing the part zero or home reference. Is used for rotating from the incremental to the absolute mode and vice versa Is used to turn the display off while keeping track of the axes position at all times. This key must be pressed before turning the unit's power off by the main switch on the back of the unit. Is used to validate an operation. Is used to cancel or abort an operation already initiated. - NVP-M - Operation Manual - Page: 1.2 -

35 Is used to display half the actual axis movement. These are dual purpose keys and are used for entering values and applying tool compensation Is used to change the sign of the entered value or change from fine to coarse resolution and vice versa. Is used for freezing the display of the feedback even though the axis moves. F Is used to access the special operation modes, parameter setting, communications via RS-232-C, etc. Are used to select the previous or next option in a menu or in a mode. EDIT Is used to access the editing mode for the tool table or program blocks. TEACH Is used for programming a part in teach-in mode by inserting blocks after moving the axes to the desired position. EXEC Is used to access the execution of a cycle or part program previously stored. 1.2 REAR PANEL (SEE INSTALLATION MANUAL) - NVP-M - Operation Manual - Page: 1.3 -

37 2. COORDINATE DISPLAY 2.1 DISPLAY MODES Turning the unit ON The unit is turned on by actuating on the power switch of the rear panel This DRO runs a self-test and its LCD screen shows the text: Fagor NVPxxx M, Press C where xxx indicates the model and the X and Y displays show "Fagor dro" if everything is OK and the error number if otherwise. See the appendix at the end of this manual. Turning the unit OFF If you press key the DRO switches off the displays while maintaining the power supply to the feedback systems and goes on reading the position of the axes at all times. This is not the case when the equipment is switched off by means of the switch on the rear panel of the same. To reset the displays, just press this key again, on condition that the DRO is getting voltage (plugged in and with the switch on the rear panel on). Notes: - Before powering the DRO down with the switch on the rear panel or disconnecting it from mains, it is a good idea to press the key in order to store the current position of the axes permanently. - If the unit is powered down with its rear panel switch or there is a power outage without previously having pressed, the DRO will keep the last position of the axes for at least 30 minutes. - The unit will display ERROR 2 when powered back up if the position reading was lost when turned off while the axes were moving or after the accidental backup period has expired without having saved the current position by previously pressing. - NVP- M - Operation Manual - Page: 2.1 -

38 Language selection On this DRO, it is possible to select the language used for displaying the help on the LCD screen. To do this: - Access parameter PAR50 (language) directly by pressing 0 inch - Press + - repeatedly until the desired language appears (English, Spanish, French, German, Italian, Portuguese, custom*) and press ENTER. Press to quit the language selection mode. "Custom" may be any user defined language. (See section 3.2 PAR52 of the installation manual). Conversion mm into inches This DRO can displayed the position of the axes in millimeters or inches by pressing 0 key depending on whether the INCH led is off or on respectively. inch Fine / coarse resolution This DRO allows a decimal digit to be switched off (coarse resolution) when the resolution is excessive, simply by pressing +. For example 0.01 instead - of Radius / Diameter: When these models are used for measuring radius or diameter, one can display twice the real displacement of the axis (diameter) by pressing 1 2. Led Φ will go on or off to indicate the double or real counting mode respectively. Notes: - This key works in this way if the installation parameter PAR04 of the axis has been preset as 2 (commutated). - If this parameter is preset as 0 (radius), this key will not affect the DRO reading and will always show the real displacement of the axis. - If this parameter is preset as 1 (diameter), this key will not affect the DRO reading and twice the real displacement of the axis will always be shown. - NVP- M - Operation Manual - Page: 2.2 -

39 2.2 INCREMENTAL, ABSOLUTE AND WITH RESPECT TO MACHINE ZERO A coordinate DRO displays the present coordinate of one or several axes. Coordinate means the distance from one point or position with respect to another chosen as reference. These DROs can display the position of the axes in incremental or absolute mode or referring to home. The figure on the next page shows the coordinates of an axis which would appear in the different modes: - In Incremental (I), when the ABS and leds are off the distance from the present position of the axis to the previous position is displayed. - In Absolute (ABS), when the ABS led is on and the is off, the distance from the present position of the axis to part zero (D) is displayed. - In reference zero ( ), when led is on, the distance from the present position of the axis to home (Io) chosen in the feedback system (scale or encoder) is displayed. To access this mode use key. This DRO offers up to 9 reference points (from 1 to 9 part zeros) which can be preset with different absolute values ("ABS" LED ON) and an incremental value ("ABS" LED OFF) common to all of them. Plus, reference "0" which is the home reference. In this mode ( on) the DRO shows the current position of the axis with respect to home (reference mark of the feedback device). - To get into this mode, press and the LCD shows "Reference Number: 1" or part zero from 1 to 9) indicating that the position of the axes are referred to that reference point or part zero.- - NVP- M - Operation Manual - Page: 2.3 -

40 - To select another reference point, just press its corresponding key [0] to [9] or the keys. Once it is selected, press to activate it or ENTER C to cancel the operation and quit this mode leaving the previous part zero. - The home reference "0" cannot be preset and it will be assumed when the DRO detects the reference pulse coming from the feedback device as described later on. Note: If parameter PAR14 = 1, it will be possible to preset the home position when using feedback devices not having a reference mark (pulse). For example FAGOR MKT series scales. To change from one of these display modes to another, press relevant led goes on or off as described earlier. until the It could occur that the installation parameter PAR11(1) has been set to 0 for key to independently affect each axis so that one axis can display its position in incremental mode whilst the other does this in absolute. In this case, to change the display mode for a particular axis, press sequence: for "X", for "Y" and for "Z". - NVP- M - Operation Manual - Page: 2.4 -

41 2.3 MACHINE REFERENCE SELECTION AND SEARCH Though it is not absolutely necessary for a large number of applications we recommend fixing a reference point (home) for each axis using the reference marks (Io) of its feedback system, whether this is a scale or an encoder in order to be able to keep the respective zeros (part and incremental) and recover these after having disconnected the equipment or for any other reason. Standard FAGOR scales have a fixed reference mark (Io) every 50 mm along their travel. When starting the home search and pressing an axis key (X, for example) the current axis position starts blinking with zeros to the left. FAGOR also offers scales with a coded Io with which all you have to do is move the axis at most 20 mm or 100 mm (depending on the model) from the present position in order to find the exact position of the axis with respect to home. When this mode is selected, the DRO waits to receive this pulse (Io) to reestablish all its previous absolute and incremental references (part zero and incremental zero). For this reason when fixed Io (not coded) scales are used, one first has to choose an approximate reference zone, for example about half way along the axis travel, take the axis up to said zone and carry out the search for the Io ( ) reference mark of the scale (or encoder). After said (Io) mark has been found, following the steps described below, this axis zone is marked with a pen or sticker in order to go back to this in later searches, recommended after having disconnected (not switched off the machine, as will be shown later on). These DROs keep the relative distance from home ( ) to part zero (ABS on) and incremental zero (ABS off) for each axis in their internal memory for about 10 years even after cutting off their mains power supply, for example, by means of the switch on the rear panel. This means that when it is necessary to reference the axes again, when the Io (home) mark is found said absolute and incremental zero values are recovered. - NVP- M - Operation Manual - Page: 2.5 -

42 The home search sequence is as follows: - Move the axis to the approximate reference zone (roughly). This step is only for fixed Io scales (not coded) - Get the DRO in home reference mode by pressing the sequence: 0 ENTER. If the LED is on, it is already in that mode. inch - Press the axis of the axis to be homed:,, (or F if the 4th axis is displayed) - Move the axis until the DRO detects the reference mark of the feedback device. This happens when the zeros to the left of the corresponding display disappear. When the reference pulse is received, the DRO presets this point with the value assigned to the installation parameter PAR10 for this axis. This value is (factory set) default 0. At the same time it recovers the relative distance from this home to the previously set part zeros (ABS) and the incremental value. - Press [Reference Number] ENTER to turn off the led and thus quit the home mode. Bear in mind that in reference mode, no other operation besides home searching and axis position display are possible. NOTE.- If PAR14=1 (feedback without reference mark -I0-), The home position may be preset in "Ref 0" mode. See the next section for coordinate preset. 2.4 AXIS COORDINATE PRESET To reset the axis display, just press: sequence: C for "X", C for "Y" and C for "Z" ( C F If the 4th axis is displayed). Using the next figure, let us imagine we wish to make a part in which three holes have to be made with the coordinates stated. It is clear that the blueprint will only reflect the incremental coordinates (I) or the absolute ones (ABS) referring to the part zero (point D in the figure) although the DRO also shows them with respect to home (Io). After referencing the axes, as was described in the previous section, we can make this part in incremental or absolute mode according to whether we chose a type of dimensions (I) or (ABS) of the blueprint. - NVP- M - Operation Manual - Page: 2.6 -
